The Internet knowledge (iKnow) measureOriginal Research ArticleComputers in Human BehaviorLabVIEW programming encourages and stimulates learner to focus on automation topics Hands-on programming ensures learner has clear understanding of automation and control LabVIEW programming encourages learner tDespite increasing development and administration of Internet surveys, tests, and many other applications to be used by employees and the general public, little is known about the knowledge individuals bring to Internet tasks. This research improves our understanding of the concept of Internet knowledge, and provides initial support for the construct validity of a new measure of Internet knowledge with respect to its factor structure, internal consistency reliability, and concurrent validity. From a practical perspective, clearer definition of Internet knowledge and the availability of a reliable measure of such knowledge can advance our understanding of how individuals develop Internet experience through its use and may also inform the process by which web sites and Internet applications are designed.Article Outline1.

At the same time it is essential to provide students with experiences in online collaboration, which is common in the engineering workplace, and to allow both on-campus and distance learning students to actively and jointly participate in class activities in hybrid on-campus/distance education course offerings. To address these challenges in the introductory communication networks course at Arizona State University, the authors have developed an online team design project in which students collaborate via a team website on a design project related to an emerging communication networks topic. The online team design project was evaluated with a thematic analysis of the interactions on the team websites, topic-specific pre- and posttests, and an attitudinal student survey. It was found that the online team communication was to a large extent devoted to managing the team and the project and that the students had overall very positive attitudes toward the project. Both students with lower and higher levels of prior project-related knowledge achieved approximately the same learning gain in terms of increased scores from pretest to posttest in the project.Article Outline1.

We believe that one cause of these failures is the difficulty in systematically accounting for the collaborative and exception-filled nature of medical work. In this methodological review paper, we highlight research from the field of computer-supported cooperative work (CSCW) that could help biomedical informaticists recognize and design around the kinds of challenges that lead to unanticipated breakdowns and eventual abandonment of their systems. The field of CSCW studies how people collaborate with each other and the role that technology plays in this collaboration for a wide variety of organizational settings. Thus, biomedical informaticists could benefit from the lessons learned by CSCW researchers. In this paper, we provide a focused review of CSCW methods and ideaswe review aspects of the field that could be applied to improve the design and deployment of medical information systems. To make our discussion concrete, we use electronic medical record systems as an example medical information system, and present three specific principles from CSCW: accounting for incentive structures, understanding workflow, and incorporating awareness.Article Outline1.

ConclusionReferencesHealthcare teams over the Internet: programming a certificate-based approachOriginal Research ArticleInternational Journal of Medical InformaticsSecurity is a critical issue for software systems, especially for those systems which are connected to networks and the Internet, since most of them suffer from various malicious attacks. Intrusion detection is an approach to protect software against such attacks. However, security vulnerabilities that are exploited by intruders cut across multiple modules in software systems and are difficult to address and monitor. These kinds of concerns, called cross-cutting concerns, can be handled by aspect-oriented software development (AOSD) for better modularization. A number of works have utilized AOSD to address security issues of software systems, but none of them has employed AOSD for intrusion detection. In this paper, we propose a model-based aspect-oriented framework for building intrusion-aware software systems. We model attack scenarios and intrusion detection aspects using an aspect-oriented Unified Modeling Language (UML) profile. Based on the UML model, the intrusion detection aspects are implemented and woven into the target system. The resulting target system has the ability to detect the intrusions automatically. We present an experimental evaluation by applying this framework for some of the most common attacks included in the Web Application Security Consortium (WASC) web security threat classification. The experimental results demonstrate that the framework is effective in specifying and implementing intrusion detection and can be applied for a wide range of attacks.Article Outline1. Introduction2.
